How Can Green Infrastructure Help to Manage Rainfall in an Urban Watershed?

Abstract

he study described in this research brief shows how the challenges in managing the increasing volumes of stormwater flows in a complex urban environment can be effectively addressed by a mix of solutions. Focused on a key watershed in the city of Pittsburgh, this analysis shows that a centralized system of stormwater management could yield cost-effective sewer overflow reduction, reduce street flooding, and provide positive net economic benefits across a range of assumptions about future rainfall and implementation costs.
